Project Description

Nanoscale Thermal Transport

Interfacial thermal resistance (ITR) plays a crucial role in nano-scale device components and surrounding/confined fluid. The behaviors and reliability of such devices strongly depend on the way the systems dissipate heat, low ITR makes system possible to reduce heat losses. Hence, I investigate the ITR under the effects of nanodomains. At LTD, my research is mostly focused on solid/liquid interfaces.

Nanoscale Fludic Transport

I perform atomistic simulations to observe the different physics between nanoflows and classical fluid transport theories. I also check the validity and limitations of the continuum hypothesis. At atomic-scales, the interface/surface forcefield becomes significant and highly affects the flow behaviors due to the very high-surface-to-volume-ratio. Density fluctuations (including peaks and valley) and apparent enhanced-viscosity are typically observed at such small scales. Therefore, the interface effects are treated via modified boundary conditions.
